The best way to claim the authorship of your own photographs is to put some watermarks with your author's stamp. But at the time of putting a watermark stamp you must be selective and not paste one that hides, warns or spoils the beauty of that photograph.
Therefore, it is best to opt for a program like PhotoX, which is responsible for adding subtle, discreet and elegant watermarks to each of your photographs. On the seal of this watermark you can put the text or image you want (for example your company logo). From PhotoX you can also define the type of text font, size, bold, italic, color, and so on.
At no time is the quality of the original photograph distorted, allowing work in JPG, BMP, PNG, PNM, RAV, TIFF, WBMP, etc. formats. In addition, with PhotoX you can convert these photographs to grayscale, as well as view them as thumbnails.
You can free download PhotoX 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
